1.4 Adsorption Dryers
Typical applications for the adsorption dryers are outdoor installations where the risk of
freezing occurs and applications with high quality requirements in terms of air dryness (PDP <
+3°C) such as the process air in process industry (food and beverage, pharmaceutical,
electronic, chemical, …).
The most common adsorption dryers are heatless regeneration adsorption dryers due to their
simplicity reliability and relatively low investment costs.
1.5 Adsorption
Adsorption is a process where specific molecules adhere to the surface of a highly porous solid
(adsorbent/desiccant) by electrostatic and molecular forces. The adsorbent is normally
formed in sphere form beads. Process of adsorption takes place while air flows through
column filled with the beads. Rate of adsorption depends on several factors (type of
adsorbent, relative humidity, inlet temperature, contact time, face velocity) and therefore
adsorption process is usually set/optimized for every individual application.
1.6 Appropriate Use
B-DRY series desiccant dryers are intended for highly efficient drying of compressed
air. This appliance must be used only for the purpose for which it was specifically
designed. All other uses are to be considered incorrect.
Specifically:
• Desiccant dryer can only be used for “GROUP 2” fluids (PED 2014/68/EU).
• Desiccant dryer can not be used for explosive, toxic, flammable, corrosive and “GROUP
1” fluids (PED 2014/68/EU).
Warning: internal corrosion can seriously reduce the safety of installation: check it during
maintenance.
The manufacturer will under no circumstances be responsible for any damage resulting from
improper, incorrect or unreasonable use.
Use genuine spare parts only. Any damage or malfunction caused by the use of non-genuine
parts is not covered by Warranty or Product Liability.
